A developer successfully designed a PCB for an RP2350-based development board with an E-ink display using Claude (Fable 5) with minimal manual intervention, following strict rules of no manual edits. The 31.8 × 37.32 mm, 4-layer board cost €26 per unit, though the design process revealed component package mismatches and routing challenges that were resolved through iteration with Claude.
